I checked the status for the initial boot by U5PVR after upgrading new firmware.

The reason is that there are additional things that are different from normal Android booting procedure.
1. Booting Android
2. Linux Operation
3. Operation related to ATV OS recommendation

Since this operation is performed,
until 01:38 seconds, After the initial boot of U5PVR, the system is still under full load.
So after power-up, for about 2 minutes after first booting after upgrading new firmware, It is best to leave it as is. ^^

Here, in the above-mentioned four image reproduction, it was not decided this way,
Only the video having the condition that the Plex can be operated optimally is reproduced,
You can now have these results. ^^

Of course, the test is based on the original reproduction only,
The smartphone was played with an external player.

There are many reasons for this
This is because you played back some formulas according to the conditions of the playback file.

Even if a 1080P file is used,
U5PVR load is 100%, it goes up ~~~ and only one can be supported. ㅠ. ㅠ.
(If video transcoding occurs, the load will take up to 100%, and only audio transcoding will work.)
